ER Fusion is an intensive reconstructive hair treatment which restores hair back to its youthful condition. The product creates a clear micro shield to seal in color and softness, while weightless quaternaries balance and self-adjust color in the hair. A complex set of amino cystines repair damage while lemon grass extracts enhance color with a high gloss. ER Fusion’s unique delivery system ensures optimum performance and lasts 30 days after each initial use.
